Ok, this is a long story. We moved into a house with an unfenced back yard; I thought I could make it work with the chickens I brought with me, but I’m starting to change my mind. But I don’t want to sell or give away my hens if they have a serious health issue. So, how do I tell? Here’s what’s going on: Started out here with 6 hens, variety of breeds, 3 years old at that time. We got four new chicks (we did check that they were vaccinated for Marek’s), and got them successfully integrated into the flock in about May of that year. In August, the health issues began. A silkie (3 yrs) got a growth on her stomach and died quickly after we noticed a problem (1 day). An Ameraucana (3 yrs) developed a pendulous crop. 2 vet visits and some work with a crop bra later, she died during the night. The vet had found coccidia in her feces and treated her for it, but thought the crop issue was probably genetic. The next spring, (this year) we had a sudden death when the hens were out in the yard. It was a Plymouth Rock (4 yrs), and it had been a cool and rainy day. She wouldn’t come out from under the deck to go back in the coop. About half the hens had diarrhea that went on for several months with no other symptoms except really stinky poop. (No blood in the feces that I could see, just really messy feathers around the vent.) They all got over it except one, who still has it. We had another sudden death later this summer. It was an Ameraucana (1 yr) who was runty and much smaller than the other hens. We were having trouble with pecking from two of the other hens, but had been keeping them separated. Two months ago, another hen (1 yr) had a prolapsed vent. After a vet visit, we decided to have her put down. About two weeks ago now the hen with diarrhea stopped walking around with the other hens and wouldn’t leave the coop. I swear she stopped eating too, but after a few days she picked back up and is back running happily around with the other hens now. She seemed to have trouble getting up on the days before she started staying in the coop, and now she seems to limp every now and then. I have tried a dewormer and tetracycline for the diarrhea, as well as probiotics (the sav-a-chick kind). The hens spend most of their time in their coop and pen, with a couple of hours loose in the yard probably every other day. Although I clean things out every week, I think cleanliness in the run is probably contributing to health problems, which is why I’m thinking of getting rid of them till I can afford to fence my yard so I can let them run all day (not just when I can keep an eye on them). They are eating Layena pellets, with some table scraps. So…my question is, is this normal? Or is there something going on here? And how do I find out? I’m open to a vet visit, although they don’t seem willing to talk about the health of the whole flock when I’ve been in before, and I’m not sure what I’d even be asking them about at this point.
